WebIn computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering. WebApr 12, 2024 · For simplicity and generality, shortest path algorithms typically operate on some input graph, G G. This graph is made up of a set of vertices, V V, and edges, E E, that connect them. If the edges have weights, the graph is called a weighted graph. Sometimes these edges are bidirectional and the graph is called undirected. copy action
